Recently I had a pet of over 15 yrs pass. Thankfully it was sudden and overall painless for the pet. We chose to have her cremated and wish to place her in her favorite spot out in the garden area. Knowing I had already engraved in some Marble and Slate. I thought I would give it another go and see how a nicer Marble and even some Granite would do.
I have laid out the test design in Aspire with a V carve and an Etching toolpath. V carve for the art work and Etching for the lettering. First design is for a close friend who just lost her Great Dane of 12+ years. My first test was in Marble
Not overly happy with the font chosen but that can be changed later. Overall the design milled just fine with a polycrystalline diamond 45 degree .2mm engraving bit. These bits are not cheap by any means but the diamond tip cut through the marble like butter over all. I expected this result from my tests before with a standard carbide 30 degree .2mm engraving bit before in marble and slate.
The design needs a few tweaks and the font needs to be changed. but over all the goal was reached and the stone will engrave with ease. DOC was .1 with a feedrate of about 80mm/m to be safe on the first tests.
Currently the same design is being done in granite.
So far the result is about the same with a bit finer edge detail showing through so far overall. More pics when it is finished.
Will now run test to color the engraving and go from there.
